It’s still a controversial topic that first moon landing and walk was a hoax or not. Some scientists believe that it was a hoax and there are some hints on video that support their claim. But none of the astronauts or NASA workers confirmed that claims. NASA claims that problems on video are coming from live conversion of coverage to TV stations.
The Apollo 12 went to Moon soon after Apollo 11. It was 19th and 20th of November 1969 and astronauts were Alan Bean and Pete Conrad. It was one of the most dangerous Moon missions because in the date of launch, weather was full of lightning strikes. When they launched, a strike hit the shuttle and electricity went out with guidance system but then shortly it came back. Apollo 12 left little video footage from Moon walking.Apollo 14 landed on Moon in February 9th 1971. Space shuttle was carrying Edgar Mitchell and Alan B. Shepard. It was planned as a two day stay by NASA. Astronauts landed on the Fra Mauro formation in Moon and it was a dream for all Apollo shuttles to land there. Astronauts collected moon rock.

Also astronauts made lots of important researches with tools like gamma ray spectrometer and mass spectrometer. NASA confirmed the shuttle as the most successful Moon mission but incidents like Apollo 15 postage stamp created some problems.Apollo 16 was one of the hardest Moon missions because of its landing place. Main target was highlands of Moon. Astronauts Charles Duke and John Young walked on the moon in this mission. Mission faced some problems and it was almost aborted. Astronauts stayed in Moon for 71 hours. Also they collected rocks from volcanic platform and these samples changed lots of old beliefs about Moon’s creation.
